About Pink Rock Jasmine
Androsace carnea · also called Pink Rock Jasmine, Flesh-pink Androsace · flowering
Pink Rock Jasmine is a delicate cushion-forming alpine from the Pyrenees and Alps, producing tight mounds of narrow grey-green leaves adorned with clusters of pale to deep pink flowers with yellow eyes in late spring. A prized specimen for alpine troughs, tufa, and rock gardens, it demands excellent drainage, full sun, and moisture-free winters.
Ideal humidity: Very low, 20–35% RH
Watch for — Winter cushion rot: The most frequent cause of plant loss. Water collecting in the hairy rosettes during cold, damp winters causes botrytis and bacterial rot. Grow in an alpine house through winter or protect with a glass pane to shed rain while maintaining airflow.
The watering schedule, season by season
Pink Rock Jasmine flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for pink rock jasmine is very sparingly; driest in winter, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
- Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
- Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.
Water modestly during active spring growth, allowing soil to partially dry between applications. In summer and especially winter, keep the crown nearly dry. Rain protection in winter (alpine house or cloche) is strongly recommended in wet climates to prevent fatal crown rot.

How to tell pink rock jasmine needs water
A calendar is the worst way to water pink rock jasmine. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch.
- Leaves or flower stems lose turgor and start to droop.
- Buds stall or the pot feels light.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering pink rock jasmine for a day is almost always safer than over-watering it.
Overwatering vs underwatering pink rock jasmine
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For pink rock jasmine specifically:
Signs you are overwatering
- Yellowing leaves, bud drop, and a heavy, constantly wet pot.
- Mushy stems or crown rot at soil level.
- Fungus gnats and a sour soil smell.
Signs you are underwatering
- Wilting, bud and flower drop, and crispy leaf edges.
- A faded, stressed look and a rootball that has pulled from the pot sides.
Erratic watering — bone dry then flooded — makes pink rock jasmine drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for pink rock jasmine unless your water is very hard; rainwater is a safe default if leaf tips brown.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For pink rock jasmine, the levers that matter most are:
- A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
- Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
- Empty the saucer after every water so the roots are never sitting in run-off.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of pink rock jasmine.
